Enhanced Ultrasound Superior to MRI for Diagnosing Certain Liver and Kidney Tumors

Contrast-enhanced ultrasound (CEUS) is a non-invasive imaging tool that is routinely used across the world to identify and characterize cancers, diagnose heart and vascular disease, monitor chronic gastro-intestinal diseases and therapy. Now, two new studies have revealed that CEUS is more accurate and reliable than MRI for examining certain liver and kidney nodules. More...

Ultrafast MRI Predicts DCIS Upgrade to Invasive Cancer at Breast Surgery

Biopsy-proven ductal carcinoma in situ (DCIS) lesions are often upgraded to invasive cancer at surgery. As a result, accurate prediction of the likelihood of invasion can be helpful for surgical planning, including the need to perform sentinel lymph node biopsy (SLNB). Now, a new study has found that ultrafast (UF) MRI provides beneficial information that can be used in surgical planning, including determining the need for SLNB. More...

World-First Benchmark for Measuring Brain Atrophy Created Using `Fake` MRIs Developed via AI

Assessing the onset and progression of Alzheimer’s using brain MRI poses a challenge as changes in the thickness of the brain's cortex are extremely small, usually in the sub-millimeter range. Now, scientists have used AI to develop a world-first benchmark for measuring brain atrophy – or thinning - in neurodegenerative diseases, including Alzheimer’s disease. More...

New MRI Method Automatically Detects Placental Health during Pregnancy

A new method can process MRI scans to reveal the distinct compartments of the placenta, measure oxygen levels in each region and identify malformations in blood vessels (i.e., placental lesions), thus improving the detection and prevention of pregnancy complications. More...

AI-Guided Image Acquisition Software Significantly Reduces Cardiac MRI Scan Time

An automated, software-only platform greatly simplifies a Cardiac MRI (CMR) exam, enabling hospitals to increase throughput for existing scanners and/or get a CMR program off the ground cost-effectively. More...

MRI Far Superior in Cancer Detection than Hand-Held & Automated Ultrasound and DBT

Screening mammography can detect about 98% of cancer in fatty breasts, but can more easily miss breast cancer in dense breasts, resulting in a negative mammogram and providing patients with a false sense of reassurance. Now, a new study has found that breast magnetic resonance imaging (MRI) is superior at detecting breast cancer in women with dense breasts as compared to common supplemental screening methods.

Accelerated MRI with AI Image Reconstruction Nearly Halves Scan Times (MI-MRI)

Artificial intelligence (AI) can reconstruct coarsely-sampled, rapid magnetic resonance imaging (MRI) scans into high-quality images with the same diagnostic value as those generated using traditional MRI, according to a new study. Reconstructing MRI scans with AI, which is four times faster than standard scans, has the potential to expand MRI access to more patients and lower appointment wait times, the study says. More...
